To ensure all wireless activities went smoothly, Shure supplied PWS with its new Axient Wireless Management Network. In addition, UHF-Rs and PSM-1000 Series IEMs and 2000 and 3000 series gear from Sennheiser were provided by ATK Audiotek. "The frequency coordinators pack us closer than the equipment can actually support, so our expertise comes into play when we’re able to manage interference by negotiating the times certain equipment is turned on and when other equipment will be turned off to avoid interference," says Eskew. "One of the reasons we used the Shure Axient Network was its ability to have a much tighter IF [intermediate frequency] strip, which then allowed us to put channels closer together—safely." PWS also took advantage of the Axient’s frequency diversity mode for automatic fail over protection of the Referees’ microphones and the diversity receiver features of the PSM-1000 IEM systems.

PWS also premiered its Domed Helical Antenna on the field for the first time since its launch in late 2011. A new standard in wireless antenna performance and physical presence, the Domed Helical Antenna combines the highly successful circular polarization configuration pioneered by the company’s original Helical, but with the unit sealed within a unique new compact “domed” design. This provides robust multichannel wireless microphone, in-ear and intercom wireless connectivity. Constructed from rugged polycarbonate, PWS’ Domed Helical is designed to hold up to considerable road-related abuse. A combination of eight Domed Helicals and seven original PWS Helicals were used for all of the ATK wireless systems on the field.

“While the Domed Helical has made appearances at concerts and other live events, the Super Bowl adds a whole new dimension to the types of applications that can benefit from the capabilities these antennas offer—from greater bandwidth and longer range gain to more flexibility in wireless communications,” says Eskew. “The Super Bowl is a major event in terms of logistics and frequency coordination and we couldn’t be more pleased to be a part of the team that makes it streamlined. We do it not only for our clients but also for the viewers in the stadium and those watching from home.”
